above are four separate commands. i want to combine the grep in each command into one awk statement. instead of using two egreps, i figure awk can do it better.
Hi
Maybe you can suggest a nicer way to do the following:
RET_STR=$(echo ${RET} | sed -e 's/0/Object is not mapped/' \
-e 's/1/Operation Internal Error/' \
-e 's/2/Operation Invalid Arguments/' \
-e 's/3/Object is mapped/' \
-e 's/4/Path not found/') (3 Replies)

Hello,
I trying to extract text that is surrounded by xml-tags. I tried this
cat tst.xml | egrep "<SERVER>.*</SERVER>" |sed -e "s/<SERVER>\(.*\)<\/SERVER>/\1/"|tr "|" " "
which works perfect, if the start-tag and the end-tag are in the same line, e.g.:
<tag1>Hello Linux-Users</tag1>

largefile - large file status of utilities
DESCRIPTION
A large file is a regular file whose size is greater than or equal to 2 Gbyte ( 2**31 bytes). A small file is a regular file whose size is
less than 2 Gbyte.
Large file aware utilities
A utility is called large file aware if it can process large files in the same manner as it does small files. A utility that is large file
aware is able to handle large files as input and generate as output large files that are being processed. The exception is where additional
files are used as system configuration files or support files that can augment the processing. For example, the file utility supports the
-m option for an alternative "magic" file and the -f option for a support file that can contain a list of file names. It is unspecified
whether a utility that is large file aware will accept configuration or support files that are large files. If a large file aware utility
does not accept configuration or support files that are large files, it will cause no data loss or corruption upon encountering such files
and will return an appropriate error.
The following /usr/bin utilities are large file aware:
adb awk bdiff cat chgrp
chmod chown cksum cmp compress
cp csh csplit cut dd
dircmp du egrep fgrep file
find ftp getconf grep gzip
head join jsh ksh ln
ls mdb mkdir mkfifo more
mv nawk page paste pathchck
pg rcp remsh rksh rm
rmdir rsh sed sh sort
split sum tail tar tee
test touch tr uncompress uudecode
uuencode wc zcat
The following /usr/xpg4/bin utilities are large file aware:
awk cp chgrp chown du
egrep fgrep file grep ln
ls more mv rm sed
sh sort tail tr
The following /usr/xpg6/bin utilities are large file aware:
getconf ls tr
The following /usr/sbin utilities are large file aware:
install mkfile mknod mvdir swap
See the USAGE section of the swap(1M) manual page for limitations of swap on block devices greater than 2 Gbyte on a 32-bit operating sys-
tem.
The following /usr/ucb utilities are large file aware:
chown from ln ls sed
sum touch
The /usr/bin/cpio and /usr/bin/pax utilities are large file aware, but cannot archive a file whose size exceeds 8 Gbyte - 1 byte.
The /usr/bin/truss utilities has been modified to read a dump file and display information relevant to large files, such as offsets.
cachefs file systems
The following /usr/bin utilities are large file aware for cachefs file systems:
cachefspack cachefsstat
The following /usr/sbin utilities are large file aware for cachefs file systems:
cachefslog cachefswssize cfsadmin fsck
mount umount
nfs file systems
The following utilities are large file aware for nfs file systems:
/usr/lib/autofs/automountd /usr/sbin/mount
/usr/lib/nfs/rquotad
ufs file systems
The following /usr/bin utility is large file aware for ufs file systems:
df
The following /usr/lib/nfs utility is large file aware for ufs file systems:
rquotad
The following /usr/xpg4/bin utility is large file aware for ufs file systems:
df
The following /usr/sbin utilities are large file aware for ufs file systems:
clri dcopy edquota ff fsck
fsdb fsirand fstyp labelit lockfs
mkfs mount ncheck newfs quot
quota quotacheck quotaoff quotaon repquota
tunefs ufsdump ufsrestore umount
Large file safe utilities
A utility is called large file safe if it causes no data loss or corruption when it encounters a large file. A utility that is large file
safe is unable to process properly a large file, but returns an appropriate error.
The following /usr/bin utilities are large file safe:
audioconvert audioplay audiorecord comm diff
diff3 diffmk ed lp mail
mailcompat mailstats mailx pack pcat
red rmail sdiff unpack vi
view
The following /usr/xpg4/bin utilities are large file safe:
